  Background and Objective: This study was implemented in 1393, aimed to evaluate reaction, learning and behavior of learners from training course and empowerment SAMEN Credit Institu IT staff to design green data center with the aim of developing the use of renewable energy and environmentally friendly technologies. Green data centers are the building for storage, management and dissemination of data, which have the highest efficiency in infrastructure design to minimize wasted resources of electricity and to achieve maximum efficiency with minimal environmental impact. Method: By the Cochran formula, 40 persons among the 45 of SAMEN Credit Institute and Samen Ertebat ASR IT experts had been considered (2014). Given the choice Kirkpatrick model, at the end of the training course, evaluation questionnaires designed in behaving and reactive level had been given to learners. Due to checking the learning level, learning questionnaires had been given to learners before and after the course. In order to analyze the data and confirm the research hypotheses, descriptive statistics (mean and frequency) and inferential statistics (KS, T-dependent and T one sample tests) were analyzed by SPSS software. Findings:Given the results of these tests, learners from teacher, contents, features and timing of course were satisfied and the education and empowerment of employees in the reaction, learning behavior has also led to increased knowledge and learning. Discussion and Conclusion: After the training, skills, thoroughness in completing tasks, work morale, job satisfaction, resolve work problems and use of learning increased and this course from a behavioral perspective lead to the desired results for improve the design of green data center.  Manuscript profile

  Nowadays, so much heat has been generated in data centers which is caused by many electronic devices. This generated heat has been increased proportionally with the number of racks in IT rooms .In other hands, the power consumption of IT cooling system is more than 43% of total electrical consumption in data centers, hence the technology of its cooling systems is very important. Selection of cooling system design should provide the most efficiency and the least power consumption. In this paper, data centers with raised floor or without raised floor will be considered and 9 air distribution procedures for air cooling of IT rooms will be discussed and will be compared. According to the number of IT’s racks and power consumption of IT’s cabinets, the best selection of air distribution options will be determined .by the results of this paper , the clients of data centers could choose the best cooling system options which are appropriate with the number of racks and the power heat generation in data centers.
